NEW ORLEANS — If there's a theme to this year's New Orleans Jazz and Heritage Festival, it may be living legends.

Headliners include B.B. King, Billy Joel, Willie Nelson, Hall and Oates and Fleetwood Mac. There's also a cast of modern day hit makers such as The Black Keys, Maroon 5, Jill Scott, Kem, the Dave Matthews Band and New Orleans native Frank Ocean.

Over the next two weekends, fans of the New Orleans Jazz and Heritage Festival will be treated to traditional jazz as well as rock 'n roll, Cajun, gospel, blues, hip-hop, funk and zydeco.
